Makita HR4013C 1-9/16" Advanced AVT Rotary Hammer

• Advanced AVT includes a vibration absorbing housing with a spring loaded back handle and housing which moves independently of the motor and hammer mechanism effectively isolating more vibration away from the user
• Advanced AVT includes an integrated damper spring at the base of the impact bolt engineered to absorb impact vibrations from the drill bit
• Advanced AVT includes an air actuated counterbalance that directs air pressure from the crank and barrel room into the counterbalance cylinders to move counterweight pistons in the opposite direction of the hammer mechanism to effectively reduce vibration
• Accepts SDS-MAX bits
• 24 bit angle settings allow the bit to be set at different positions and One-touch sliding chuck for quick bit changes

The powerful 11 AMP motor delivers 11.4 Joules (8.4 ft. lbs.) of impact energy, 20% more than the previous model for faster drilling. The rotary hammer includes an Advanced Anti-Vibration Technology (AVT), which is a synchronized, three-component system that more effectively reduces vibration resulting in a low 5m/s2. It has constant speed control that automatically applies additional power to the motor to maintain speed under load to complete the most challenging jobs. The variable speed control dial enables user to match the speed to the application for greater versatility. Torque limiting clutch engineered to prevent gear damage by automatically disengaging gears if the bit binds. Includes L.E.D. power lights and service lights. The L.E.D. power light indicates switch failure or cord damage and the L.E.D. service light notifies the user approximately 8 hours before the brushes need to be replaced. The rotary hammer has 2-mode operation for "Chipping Only" or "Hammering with Rotation", Lock-on or trigger activation in "Chipping Only" mode with a push button start/stop control for more convenient operation. Includes: D-Handle Assembly(196792-8), Depth Rod(331955-1), Side Handle Assembly(123138-5), Hammer Bit Grease(194683-7), Cloth F-Wiping Oil(443122-7) and Accessory Case(0000).
